Boric Acid (NORMAL SULFATE GRANULAR)

Boric Acid Technical Grade, Granular, Normal Sulfate is the most widely used standard industrial form of orthoboric acid (H₃BO₃). It is manufactured globally by major suppliers such as Eti Maden and distributed by Etimine USA.

The term "Normal Sulfate" distinguishes this standard industrial material from specialty "Low Sulfate" or "Ultra-Low Sulfate" grades, which are specifically reserved for highly sensitive applications like nuclear engineering and high-end electronics processing.

Because it contains standard trace levels of sulfate, this product group serves as a highly cost-effective boron source for heavy industries that do not require ultra-low sulfur limits:
- Textile Fiberglass & Glassware: Acts as a strong fluxing agent, dropping melt temperatures, boosting chemical resistance, and improving the thermal shock durability of borosilicate glass.
- Ceramic Glazes & Frits: Used to bind formulations and control thermal expansion, resulting in more durable ceramic glazes and vitreous enamels.
- Flame Retardants: Incorporated into cellulose building insulation, timber treatments, and wood composites to naturally suppress flames and inhibit smoke development.
- Agricultural Micronutrients: Blended into commercial granular fertilizers or soil treatments to correct boron deficiencies in high-yield crops.
